The data explorer is updated with live data only once per month, usually the first of the month. Perhaps you have to wait a few days to see the desired data.

Note that it is different for different sites. A lot of people are suggesting your Meta.SO account, which is all fine and good, but if you want ELU or SO, you need to check those IDs on the user page for that particular site.

@drm65 - I don't know. That is your profile. How long have you been a member of EL&U? The data explorer data is always at least one month out of date. So if you're less than a month on the site you won't appear just yet.

@drm65 ChrisF is correct. That query works for other userIDs whose owner joined earlier than you.

@ChrisF: Ahhh... that must be it. I've only been on SE for 29 days.

The 2nd way doesn't work anymore. Can you confirm and update your answer ?

@MichaelMrozek: Actually, to be honest, I'm writing a PHP library for the API and I needed a single answer somewhere that clearly described how to retrieve a user's ID. None of the other answers seemed to do that.

+1 this answer is indeed more clear than the others.
